He thought hard for a moment, considering and discarding various plans, until he struck upon one that seemed workable. "Ontrodes has plenty of room in his tower. I am sure that a gold crown will purchase a night's stay and cheerful hospitality in an atmosphere of rustic scholarship and charming antiquity." At once Jack alighted from the rooftops and set off toward Shadystreets, splashing through the rain-soaked streets and whistling merrily to ward off cutpurses and murderers lurking in the dark alleyways of the poorer neighborhoods.

He reached Ontrodes's street and picked up his pace, anxious to be inside. Few streetlights burned in this part of the city, and the evening here had a restless, watchful feel to it, as if unseen eyes studied his every move in breathless patience. Jack hurried about halfway down the street and then stopped in confusion.

"Evidently, I am more intoxicated than I thought," he muttered. "Ontrodes's tower is not on this street, which begs the question, which street am I on?"

He halted and looked about to get his bearings. On his right hand stood the Dyddow Barrelworks, exactly where it was supposed to be at the end of Riverview Road, and he'd just passed the Red Ravens firefighters' hall on his left not fifty yards back. This was the right spot, but Ontrodes's tower was not here. Narrowing his eyes suspiciously, Jack turned in a slow circle, studying his surroundings carefully on the off chance that some incredibly ambitious trickster had moved the sage's tower in order to have a hard-earned laugh at his expense. A dilapidated house joined to a shapeless mound of rubble caught his eye.

"Wrack and ruin!" Jack cried. "Ontrodes's tower has finally collapsed entirely!" And indeed, the precarious angle at which the sage's small round tower had leaned for years evidently proved too much for mere stone and mortar to bear. The small house still stood, although it leaned drastically in the other direction now that it had been freed of the tower's pull. The stone archway joining house to tower remained more or less intact and was now covered loosely by a ragged piece of canvas that hung damply in the rain. Books and fragments of books lay crushed beneath the rubble or strewn here and there across the muddy streets.

Jack shook himself out of his amazement and bounded up to the cottage door. He cast one more glance at the stones piled up beside him, and then hammered on the door to the sage's dilapidated demesnes.

"Ontrodes, Ontrodes! Open up! I have urgent business with you!"

There was no immediate response, so Jack decided simply to hammer continuously on the door until he provoked one. Certainly the sage's neighbors began to express their dissatisfaction after a few minutes of Jack's attention, screeching obscenities out of open windows and threatening him with horrible violence if he didn't cease and desist.

After two or three minutes of incessant hammering, the door was suddenly thrown open from within. Ontrodes, dressed in a wine-stained robe, stood there, rubbing his eyes blearily as he stared at Jack. "What harm have I ever done to you, you impudent whelp? Have you not done enough? What is it to be now?"

Jack paused and rubbed the heel of his hand, somewhat sore from pounding on the sage's lintel. Ontrodes stared at him with undisguised contempt, even anger, but that of course was to be expected when waking the old codger in the middle of the night.

"Wise Ontrodes, what has become of your domicile? What catastrophe befell your noble residence?"

The sage's face darkened into a drunken, bitter anger so vehement that Jack took a step back. "You ask me what became of my tower? You ask me? By Gond's wondrous brass balls, Jack, do you think that I find anything amusing about this? I am a peaceable man, a man of wit and learning, but I swear by Cyric's black heart that if I ever catch sight of you again, I will pull off your head and defecate down your throat!"

With that the sage slammed his door so thunderously loudly that two more stones jutting out from the maimed wall of his home clattered down onto the rubble, and the door-latch flew from its place to land in the mud at Jack's feet.

"That," thought Jack, "was not the expected result of this conversation."

He walked in a small circle, thinking hard. Ontrodes was clearly incensed-no, enraged-at him, but he still needed shelter and he did earnestly desire to understand exactly what he had done, other than waking the man in the middle of the night, that could possibly have earned him such vitriol. He wrapped his arms around his torso and stamped, growing chilled in the damp night air. The old dwarven bottle was round and warm in his coat pocket.

Gingerly, Jack stepped up and rapped his knuckle on the door. "Ontrodes!" he called softly. "I do not know how I have caused you such anger, but I would dearly like the opportunity to make amends. I have brought you a distillation concocted by old Cedrizarun himself, seized just yesterday from the jaws of a dragon in the Guilder's Vault! Please, allow me to make a gift of it to you!"

The sage snuffled and grunted in his cottage, but remained silent for a long time. Jack began to fear that he might not reply at all, but finally the door creaked open again.

"I do not believe you," the sage said through an inch-wide gap, "and there is no liquor on the face of the world that could possibly atone for the wrong you have done, but, just for the sake of curiosity-show me."

Jack withdrew the dark bottle from his coat and held it up for the sage to see. "I found it in Cedrizarun's tomb," he said quietly. "Look at the bottle. It matches precisely the bottle Zandria showed you, does it not?"

"You probably stole it from her, poured out the contents in ignorance, and filled it with swill," Ontrodes said, "but the bottle itself may be valuable. Give it to me!"

"First, wise Ontrodes, noble Ontrodes, I wish to know: Why are you angry with me?"

The sage's face reddened, but with the prize suspended before his eyes, he managed to retain a deadly calm. He waved one hand at the wreckage of his tower. "Is it not obvious?"

"You believe that I caused the collapse of your tower?" Jack snorted in amazement. "Ontrodes, the tower was decrepit. It might have fallen for any number of reasons. I certainly had nothing to do with it."

"Oh? I thought that the magical blasts you used to destroy the beams holding up the second floor hastened my tower's demise considerably!" Ontrodes snapped. "How can you stand there pretending innocence, when not six hours past you were dancing around my crumbling home, singing those inane, insulting limericks and hurling blast after fiery blast into my very home! Why, if I hadn't thrown myself out the window of the study, I would have been killed!"

"I have no memory-" Jack began, and then he halted. Of course he didn't have any memory of wrecking the sage's tower, because he did not do it. But was it not possible, perhaps even likely, that his shadow had been here instead? "Ontrodes, believe this or not, but it is the truth: Two days past I discovered that I have a sinister and malicious copy at large in the city, a spiteful fellow who wears my likeness and apparently delights in tormenting my friends and acquaintances. My doppelganger wrought the ruin of your tower."

The sage merely blinked at him. "You expect me to believe that? What an incredibly convenient explanation!"

"I had thought I might call on you and ask for shelter for the night," Jack continued, stroking his beard, "but now I see that I have need of your professional services too. Here, I freely offer you this rare and exceedingly valuable dwarven brandy by way of apologizing for my counterfeit's uncouth actions." He handed the sage the bottle from the Guilder's Vault and then stepped inside, easily avoiding the old man's groggy attempt to impede him at the door. He would have gone straightaway to the sage's study, but that of course no longer existed, so he turned instead into Ontrodes's kitchen and drew up a chair by the hearth. "Now what are the means by which some villain might copy one's appearance or create an evil duplicate of a person?"
